Etude par modélisation de la commande optimale des systèmes de chauffage des bâtiments utilisant des chaudières à charbon

Abstract : Heating systems using coal-fired boilers in buildings with discontinuous occupation have specific characteristics. The work presented here was focused on the study of the energy management of such systems. Two coal-fired boiler models were developed: a comprehensive model and a simplified model. The comprehensive model was developed so as to describe the dynamic behaviour of the boiler. The simplified model was developed in order to meet the control calculation needs. An optimal control structure based on the quadratic optimization principle was designed, improved and adapted to the intermittent heating system control. When supplemented with a self-adjusting method, this control can automatically correct the control errors either caused by the inaccuracy of the model used or resulting from other factors. Studying by simulation the optimal control as applied to coal-fired boiler heating systems has proved the efficiency and flexibility of this control; furthermore, the saving of energy made by this method, as compared with a stadard control, is important.
